What are the practical implications of your pessimism?

I spend a lot of time with my family rather than chasing dead ends :)

I don’t understand. Are you a physicist? Why does being pessimistic about fusion give you more free time?

[pointyhat]

Without going on too much of a philosophical tangent; not about fusion - about everything in general. It allows me to concentrate on now rather than in the future. Now is the only time that is certain. Now is the only time you get to enjoy your life before it's over or your children leave.
